Real engineering for broken apps.
We find the root cause — and fix it.
AI tools can generate code in minutes, but when your app crashes, WebRTC streams drop, or store reviewers reject your build, AI hits a wall. We bring deep technical fundamentals across Mobile Tech, Web Tech, and WebRTC. Whether you need an urgent rescue or want to turn an idea into a published app in 30 days — we get it done.
Deep technical fundamentals across Mobile, Web, and Real-Time.
Whether your app was hand-coded, built by an agency, or scaffolded with AI, we troubleshoot and build at the foundation level — solving the deep architectural issues that surface-level patches miss.
$ WebRTC & Real-time Media
Video & audio dropouts, echo, ICE/TURN NAT traversal, latency, privacy indicators, and custom engine builds. We've even patched the core WebRTC engine itself.
$ Native Android
Kotlin & Java, Jetpack Compose, Coroutines, Room, Paging3, HILT/Koin, Firebase. Crashes, ANRs, memory leaks, and Google Play vitals diagnosed at the source.
$ Native iOS
Swift & SwiftUI, UIKit, Xcode Instruments. Memory leaks, background execution, push notifications, and App Store submission blockers resolved.
$ Modern Web Applications
High-performance web applications, responsive SPAs, real-time dashboards, WebSockets, hydration bugs, and frontend speed optimization.
$ Cross-platform (KMP/CMP)
Kotlin Multiplatform & Compose Multiplatform. Clean shared business logic across Android, iOS & Web without platform breakage.
$ Flutter
Dart, custom widgets, native platform channels, and state management. Jank, crash loops, and native-integration bugs eliminated.
$ React Native
TypeScript, Redux/Saga, MMKV, bridge communication, and UI thread freezes. Production-only bugs and bundle performance issues.
$ Store Submissions & Security
Google Play Store & Apple App Store rejection resolution, ProGuard/R8 obfuscation, SSL pinning, and release pipeline setup.
Have an idea? We'll take it to the app market in 30 days.
You don't need a bloated team or months of stalled development. If you have a clear vision, we work directly with you to turn that concept into a production-grade, published mobile or web app in four structured weeks.
Concept & Architecture
Define core user flows, technical architecture, database schemas, and wireframes. Clear scope with zero wasted motion.
High-Velocity Build
Rapid implementation using clean, maintainable architecture across iOS, Android, or Web. Real functional builds in days.
Polish & Device QA
Real-device testing, edge cases, offline handling, error states, and performance tuning so the app runs buttery smooth.
Store Submission & Launch
App Store and Google Play guidelines compliance, store assets, signing, review management, and live release.
Built it with AI — and now you're stuck?
Tools like Cursor, Bolt, Lovable, and Replit make prototyping fast. But when real-world complexity hits — race conditions, memory leaks, native lifecycle crashes, background sync failures, or mysterious store rejections — AI models hallucinate or run in circles. They don't understand the OS kernel or real hardware. We do.
$ Untangle & Refactor
AI code generators often churn out tangled spaghetti code with duplicate states and hidden antipatterns. We restructure your codebase into clean, modular, maintainable architecture.
$ Solve Deep Edge Cases
Subtle threading race conditions, native bridge disconnects, and OS-specific bugs leave AI models stumped. We trace the root cause down to system APIs and resolve it permanently.
$ Release & Store Approvals
Hit a wall with Apple App Store or Google Play review guidelines? We configure bundle signing, native permissions, privacy manifests, and compliance to get you published.
We go deeper than most teams ever do.
Most teams stop at the surface — restart the SDK, ask an AI prompt to guess, bump a dependency version, and hope it goes away. We dig until we find the real cause. Case in point: we found and fixed a bug inside the WebRTC engine itself — the real-time video/audio code that countless calling apps around the world depend on — built a custom version, and shipped it to production.
That's the level we work at. Whether it's a stubborn crash, a memory leak, a dropped video call, or a release Google keeps rejecting, we don't guess — we trace it to the root and fix it for good.
- Calls dropping or failing to connect on cellular/Wi-Fi
- Audio/video freezing, echo, or one-way media streams
- ICE candidate / TURN / NAT-traversal connection failures
- Mic / camera indicator & privacy-UI OS mismatches
- Engine-level fixes & custom SDK builds
Sound familiar?
If you're nodding at any of these, you don't need another generic developer. You need engineers who understand technical fundamentals and solve root causes.

What we've built, fixed, and shipped.
We've solved complex engineering hurdles across mobile, web, and real-time systems. A few examples demonstrating our depth — including publicly verifiable code contributions.
Fixed a bug in the WebRTC engine itself ✔ verifiable
We diagnosed and fixed a privacy bug in Google's open-source WebRTC engine that powers real-time calling apps worldwide, and shipped our custom build into production.
See the public fix on Google source →Rescued live video streaming pipelines
Tracked down and eliminated severe camera streaming freeze bugs in a live video application, deploying custom native builds directly to production.
Apps that work completely offline
Engineered an offline-first mobile sync architecture using embedded databases and on-device brokers, keeping devices synchronized without internet connectivity.

Frequently Asked Questions
How do quotations and pricing work?
We provide transparent, fixed-fee quotes based on your exact scope — whether it's a focused bug rescue, untangling an AI-built app, or a 30-day launch sprint. You know the exact cost and timeline upfront with zero surprise hourly bills.
Can you really take an idea to the app store in 30 days?
Yes. For founders with a defined concept, we run a focused 4-week sprint: Week 1 for architecture and specs, Weeks 2–3 for high-velocity build and polish, and Week 4 for QA, compliance, and App Store / Google Play submissions.
Do you only work on WebRTC?
No. While WebRTC is our deepest specialization, we work extensively across Native Android, Native iOS, Flutter, React Native, Kotlin Multiplatform, and modern Web stacks.
How do you help with AI-generated apps (Cursor, Bolt, Lovable)?
AI tools are great at generating code, but often produce subtle state bugs, memory leaks, and native integration failures. We audit your codebase, fix the broken logic, resolve build errors, and ensure it passes store reviews.
Will you need access to our source code?
For code-level fixes, yes. We are happy to sign an NDA before you share your repo, or we can begin by analyzing logs, screen recordings, or staging builds. Your IP and data remain strictly confidential.
How quickly can we get started?
Typically within 24 to 48 hours of your inquiry. For urgent production-down emergencies, we prioritize same-day review where possible.
Have an app that needs fixing, or an idea ready to build?
Tell us about your app, the problems you're facing, or the concept you want to launch. We'll evaluate the scope and send over a clear quotation and timeline.
